摘要： A first network node of a cellular system is configured for communication with a second network node over a twisted pair wire. The first network node includes a receiver for receiving, over the twisted pair wire, an intermediate frequency signal from the second network node, which intermediate frequency signal has been converted from a high frequency signal having a frequency higher than the frequency of the intermediate frequency signal by the second network node, and a down-converter for converting the intermediate frequency signal to a low frequency signal having a frequency lower than the frequency of the intermediate frequency signal. The first network node also includes an up-converter for converting a received low frequency signal to an intermediate frequency signal having a frequency higher than the frequency of the low frequency signal.

摘要： Method and arrangement in a Vectoring Control Entity, VCE, for handling disorderly events in a Digital Subscriber Line, DSL, system. The method involves a number of actions, to be performed when a disorderly event occurs on a line min a vectored group of DSL lines, and the transmission on line m is continued. The method comprises obtaining (104) error samples from Customer Premises Equipments, CPEs, connected to other lines in the vectored group of DSL lines. The method further comprises—calculating an estimate of the channel coefficients changed due to the disorderly event, based on the error samples, thus providing a partial channel estimate. Further, the method comprises—modifying (110) a downstream precoder, at least partly based on the partial channel estimate, such that retraining of the other lines in the vectored group due to the disorderly event is avoided. The arrangement is adapted to enable the performance of the above described method.

摘要： A method and arrangement are disclosed in a Vector Control Entity for enabling a fair bit rate distribution among lines of similar priority in a vectoring group, when applying partial vectoring in a DSL communication system. The method comprises calculating a rate balancing metric, RBM, for each line i within a priority group A, indicative of the ratio between the bit rate of a line i with a current vectoring resource allocation, and the estimated bit rate of line i assuming approximately no crosstalk within the vectoring group. The method further comprises allocating partial-vectoring resources to the line/s within the group A, based on the calculated RBMs, such as to reduce the difference in RBM between the lines. The method further comprises calculating an updated RBM for any line within the group A subjected to changes in vectoring resource allocation. The method may be iterated until certain criteria are fulfilled. The arrangement is adapted to enable the performance of the above described method.

摘要： When data retransmission is used to handle errors caused by impulse noise, buffer memory requirements may be reduced and/or data rate increased by detecting impulse noise at the transmitting equipment and initiating retransmission in response to such detection rather than waiting for a retransmission indication from the receiving end. The decision to retransmit may be made dependent on the strength or other properties of the detected noise burst. The decision criterion may be made adaptive by correlating noise burst properties with received retransmission indications or the absence thereof.
